Oase BioMaster² 850 External Aquarium Filter

New generation of external filters. The BioMaster² meets the highest demands for filtration and water clarity. The combination of highly effective biological filtration thanks to Hel-X and mechanical-biological cleaning through filter sponges ensures healthy and clear aquarium water. Depending on the model, the BioMaster² is suitable for aquariums with a volume of up to 850 liters. Thanks to optimized water flow and a new connection set, the flow rate has been significantly increased compared to the previous model. Additionally, the actual energy consumption has been reduced, so that consumption under operating conditions is lower than the nominal value. Faster maintenance: the EasyClean pre-filter allows for convenient filter cleaning. The safety lock prevents accidental water leakage, for example when removing the pre-filter module. A practical priming button makes water aspiration a breeze and allows for quick and convenient start-up. The complete set includes filter media, hoses, adapters, inlet and outlet pipes, and the water diffuser, so the external filter can be used immediately. The BioMaster² is available with or without a heater.

• EASYCLEAN PRE-FILTER MODULE: No more dismantling the entire filter: The pre-filter module is simply removed, rinsed, and reinserted.
  

• INCREASED FLOW RATE: Thanks to optimized water flow and a new connection set, the flow rate has been significantly increased compared to the previous model.
  

• LARGE FILTER VOLUME: The perfectly matched combination of highly effective biological filtration from Hel-X and mechanical-biological cleaning with filter sponges ensures healthy and clear aquarium water. Water first flows through the pre-filter for extra long life.
  

• LONGER LIFESPAN: For an even longer lifespan, you can use our biological filter media.
  

• OPTIMAL FILTRATION: Fine 30 / 45 ppi pre-filter sponge for optimal mechanical filtration of coarser dirt and extended lifespan of biological media.
  

• PRACTICAL: Venting button for efficient water priming: for quick and easy start-up during installation and after cleaning.
  

• SECURE: The locking mechanism facilitates disconnection from the water circuit. Thanks to the safety interlock, accidental water leakage is avoided.
  

• ECONOMICAL AND QUIET: Operates quietly and saves energy.
